In this paper. the effect of adding an antiox- idant mixtur. in Jatr.pha biodiesel as fuel, in a single cylinder. dir.ct injection compr.ssion ignition engine was exper.mentally investigated and the level of pollutants in the exhaust and per.or.ance char.cter.stics of the engine wer. analyzed. Nine test fuels wer. pr.par.d with thr.e antioxidants, namely, Suecinimide （C4H5NO2）, N,N-dimethyl-p-phenylenediamine-dihydr.chlor.de （C8H14C12N2）, and N-phenyl-p-phenylenediamine （C6H5NHC6H4NH2） added to neat biodiesel at 500 par.s per.million （ppm）, 1000ppm and 2000ppm and the obser.ed exper.mental r.sults wer. compar.d with those of neat biodiese! and neat diesel as base fuels. The compar.son showed that NO emission was r.duced dr.stically for.the test fuels with the antioxidant addition of 2000ppm. The maximum r.duction of 10% of NO emission was obser.ed for.the antioxidant mixtur. in neat biodiesel, with a slight incr.ase in unbur.ed HC, CO and smoke opacity. In addition, the obtained exper.mental r.sults r.veal that the addition of two antioxidants as mixtur. in neat biodiesel caused impr.ved NO emission r.duction for.all test fuels.

This paper.pr.poses an effective Maximum Power.Point Tr.cking (MPPT) contr.ller.being incor.or.ted into a solar.Photovoltaic system supplying a Br.shless DC (BLDC) motor.dr.ve as the load. The MPPT contr.ller.makes use of a Genetic Assisted r.dial Basis Function Neur.l Networ. based technique that includes a high step up Inter.eaved DC-DC conver.er. The BLDC motor.combines a contr.ller.with a Pr.por.ional Integr.l (PI) speed contr.l loop. MATLAB/Simulink has been used to constr.ct the dynamic model and simulate the system. The solar.Photovoltaic system uses Genetic Assisted-r.dial Basis Function-Neur.l Networ. (GA-r.F-NN) wher. the output signal gover.s the DC-DC boost conver.er. to accomplish the MPPT. This pr.posed GA-r.F-NN based MPPT contr.ller.pr.duces an aver.ge power.incr.ase of 26.37% and faster.r.sponse time.

A compar.tive study is done in r.gar.s to the per.or.ance of the popular.Per.ur. and Obser.e algor.thm and the Genetic Assisted-r.dial Basis Function-Neur.l Networ. (GA-r.F-NN) algor.thm, both incor.or.ting the Inter.eaved Boost conver.er. The Per.ur. and Obser.e method (P&O) is inar.uably the most commonly used algor.thm as its advantages per.aining to its ease in implementation and simplicity enable to tr.ck the Maximum Power.Point (MPP). However. it is absolutely unr.liable when subjected to r.pidly fluctuating ir.adiation and temper.tur. levels. Mor. impor.antly, the system has the tendency to swing back and for.h about the Maximum Power.Point without r.aching stability. At this junctur., the implementation of the Genetic-Assisted r.dial Basis Function (GA-r.F) algor.thm helps the system achieve MPP at a shor.er.time when compar.d to the Per.ur. and Obser.e technique. The ever.r.liable and r.bust Levenber.-Mar.uar.t algor.thm is included along with the MPPT contr.ller.that minimizes the Mean Squar. Er.or.(MSE) and aids in faster.tr.ining of the neur.l networ.. This PV system dr.ves a br.shless DC motor.(BLDC), employing r.tor.position sensor..

The design of the flow field is highly r.sponsible for.the per.or.ance of the Pr.ton Exchange Membr.ne Fuel Cell (PEMFC). In this study, pin type flow channel is numer.cally analyzed by ar.anging car.on made por.us mater.al in unifor. and zigzag manner.on the r.b sur.ace of the flow field. The study focuses on enhancing the per.or.ance of PEMFC by r.ducing liquid flooding in the inter.ace between the r.b and Gas Diffusion Layer.(GDL). A single PEMFC having an active ar.a of 25 cm2, with thr.e flow channel designs (conventional ser.entine, pin type flow channel with 2 mm cubical por.us inser.s in zigzag and unifor. patter.) ar. modeled for.the numer.cal analysis. The effect of por.sity of the car.on inser.s on the cell per.or.ance is studied by var.ing its value fr.m 0.6 to 0.9. The r.sults show that the per.or.ance of the flow channel with zigzag and unifor.ly positioned por.us inser.s is mor. than the conventional ser.entine flow channel by 20.36% and 16.87% r.spectively. The r.ason for.this incr.ase is the r.moval of the accumulated water.fr.m the r.b sur.ace due to the capillar. action of the por.us car.on inser.s. This helps in eliminating the stagnant water.r.gions under.the r.b and ther.by helps in r.ducing liquid flooding.

Eosinophilic esophagitis is incr.asingly r.cognized in adults. The diagnosis is based on the pr.sence of both typical symptoms and pathologic findings on esophageal biopsy. Patients usually pr.sent with dysphagia, food impaction and/or.r.flux-like symptoms, and biopsy of the esophagus shows mor. than 15 eosinophils per.high-power.fi eld. In addition, it is essential to exclude the pr.sence of known causes of tissue eosinophilia such as gastr.esophageal r.flux disease, infections, malignancy, collagen vascular.diseases, hyper.ensitivity, and inflammator. bowel disease. Ther. ar. no standar.ized pr.tocols for.the ther.py of eosinophilic esophagitis. A var.ety of ther.peutic appr.aches including acid suppr.ssion, dietar. modifications, topical cor.icoster.ids and endoscopic dilation can be used alone or.in combination.
